thatthe operator is forced to use some large 1 on cumbersome vessel rwithout the assistance of a funnel, with the result that the wateris 'spilled over the hose andother parts :of the car incident to the "filling of the radiator. It is for the purpose of overcoming this di-fii'cu'lty and the objection to the wetting of" the hood and *other parts of the vehicle that the present invention. has beendevised.

The chief characteristic of this invention resides in the provision of a collapsible funnel adapted" to be normallyhoused-within the filling tube, so that its use may be emplayed at any time 'clesired the-3 funnel: being adaptedto 'be projected above the r filling tube andj subsequently I expanded, i after the cap of'the filling tube has been removed.

In carrying out the invention, I provide means for automatically projecting the 'funnel above the fiil'ling tubesubsequent to the removal of the cap therefor, as well as means for automatically exp anding; the fun nel when sorprojected',athes funnel when normally arranged within the tube beingwheld immovable by: 3,. latch' which. is arranged to bewconveniently manipulated: to effect. a re: leaseiof the funnel when its use is; desired.

Hereafter thisa'housi ng. 11 will be referred to: ias the .=fillingtube, 1 inasmuch as it is in reality a part of such tube -whet-he1=2 integral'ly or sep'arably *connected therewith, and-the i-term zfillll'llg tube for this. part willwalso be mad'eause ofin the; claims. Ifhe filling itu'be is provided with ea COVBIMIQ which. is hingedlyasupported upon the tube in the manner shown. in Figures errands). This cover is "provided with a gasket 1 14' which. of course prevents: leakagei when the cover is closed. Thehinge is preferably constructed in the manner shown in Figure 9- wherein: a substantially Ur-shaped element 113 is pivoted within a bracket 1 f securedi to thatipartaof the flirting tube indicatematl 11, the terminals "of? said 1 element :1'3': beingelement 19 in holding the cover effectivelyv closed. Projecting beyond the forward end of the cover is a wire loop 20 which is adapted to be engaged by the hook like portion 21 of the latch 19, the latch being pivoted on" the portion 11 of the filling tube, as

" clearly shown in Figures 1 and 4. Any

other suitable means however, may be utilized to hold the cover in a closed position.

The funnel is of a collapsible character, which allows the funnel to be housed within the portion 11 of the filling tube, and when projected therefrom, the funnel is expanded to provide a funnel of suitable size for the purpose for which it is intended. The funnel is of oblong contour in plan, and is made up of companion end sections 22 and intermediate sections 23, the latter being posi tioned within the end sections which are mounted for pivotal movement toward and away from each other. The pivots for said end sections are indicated at 25. The upper ends of the intermediate sections 23 project above the corresponding edges of the end sections, and are turned downwardly as at 26 in the formation of channels which receive the end sections to guide the latter in their movements toward and away from each other. These down turned portions 26 of the intermediate sections assist in holding the parts operatively associated, while the end sections are further guided in their pivotal movements by means of pins 27 supported by the upper ends of the intermediate sections, and which pins are received by arcuate shaped slots 28 formed in the end sections. Then again, the end sections adj acent the lower ends are formed with short curved slots 29 which receive the stops 24 and 25 and by reason of this construction the end members are limited in their outward movements away from each other under the influence of the spring utilized to expand the funnel after it has been projected to a position for use. This spring just referred to is formed from a single length of resilient wire and is wholly disposed within the funnel, the intermediate portion of the spring being formed with a resilient coil 30, while the terminals of the spring which is of substantially V-shaped formation is passed through openings in the end sections as clearly shown in Figure 3. It was hereinabove stated that the funnel was automatically projected above the filling tube when its use was desired, and for this purpose I utilize a bell shaped. spring 32 which is wholly disposed in the portion 11 of the filling tube, one end of the s ring i 1ulus'33, the latter being riveted or otherwise suitably secured as at 34 to an appropriate part of the filling tube. Attached to this annulus 33 by the same rivets or fastening elements 34 are a plurality of loop like elements 35, preferably two in number arranged diametrically opposite each other, and which elements 35 project a slight distance above the annulus 34 to receive the lowermost convolution of the spring 32. In this manner the lower end of'the spring is fixed to the filling tube while the upper end is attached to the lower extremity of the funnel. For the purpose of attaching the uppermost convolution to the funnel I extend the lower ends of the intermediate section 23 thereof beneath the corresponding lower edges of the sections 22, and curve the said lower extremities of the intermediate sections upwardly as clearly shown in Fig ures 4 and 5, at 36. These curved portions 35 receive the adjacent convolution of the spring 32, so that when the funnel is collapsed and depressed to wholly-position the funnel within the portion 11 of the filling tube, the spring 32 is compressed, to sub sequently function to automatically project the funnel above the'tube for use.

One of the downward turned portions 26 of the intermediate section 23 of the funnel is provided with a slot or opening 37 as shown in Figure 5, and this slot is adapted to receive a pin 38 carried byone end of a fiat spring 39, which spring is secured to the portion 11 of the filling tube at a point adjacent the upper end thereof. The ,fiat spring is arranged horizontally and the pin 38 projects through an opening formed in the filling tube, so that after the funnel has been positioned within said filling tube, the spring 39 can be manipulated to position the pin 38 within the opening or slot 37 above referred to, and this of course holds the funnel within the filling tube against the influence of the spring 32. When it is desired to use the funnel it is only necessary to swing the cover 12 to the position shown in Figure 4, and subsequently pull outwardly on the fiat spring 39, which of course releases the funnel. The spring 32 then functions to automatically project the funnel above the tube 11, while the spring within the funnel operates to automatically expand OIBX- tend the funnel as shown in Figure 3. Suspended from the funnel by means of a chain or other flexible element 41 is a stopper or plug 42 which is adapted to be positioned within the overflow pipe 43, to prevent water from ente'rin this pipe while the radiator is being. fi-l ed. The plug stopper 42 is provided with a cap 44 which extends beyond the overflow pipe or tube 43 as shown and reposes upon the upper end of the tube to support the plug 42 in the position shown in Figure 4. The chain 41 may be attached to the funnel in any suitable manner, but is preferably supported from a hook 45.

\Vhile it, is believed that from the foregoing description, the nature and advantages of the invention will be readily ap parent, I desire to have it under-stood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim:

1. In combination, a collapsible funnel adapted to be normally housed within the filling tube of a radiator, yieldable means for automatically projecting the funnel above the tube for use, and a cover for holding the funnel within the tube against the influence of the aforementioned means.

2. In combination, a collapsible funnel adapted to be normally housed within the filling tube of a radiator, yieldable means for automatically projecting the funnel above the tube for use, means for normally holding the funnel within the tube against the influence of the aforementioned means, and resilient means for automatically expanding the funnel when projected.

3. In combination, a collapsible funnel adapted to be normally housed within the filling tube of a radiator, said funnel being substantially of oblong contour in cross section and including intermediate sections, and companion end sections pivoted on said intermediate sections for movement toward and away from each other, and means for automatically projecting the funnel above the tube for use.-

4. In combination, a collapsible funnel adapted to be normally housed within the filling tube of a radiator, and including opposed intermediate sections, and companion end sections pivoted on the intermediate sections for movement toward and away from each other, means for automatically projecting the funnel above the tube for use, means for normally holding the funnel within the tube against the influence of the aforementioned means, means for automatically expanding the funnel when projected, and means for limiting the movements of said end sections to these expanded positions.

5. The combination with the fillin tube of a radiator, of an extension for said tube, a collapsible funnel adapted to be normally housed within said extension, means for automatically projecting the funnel above the extension for use, means for normally holding the funnel positioned within the extension against the influence of the aforementioned means, and means for automat ically expanding the funnel when projected.

In testimony whereof I affix my signature.

EDWARD L. DAILEY.
